Having an issue with Error 400 "The specified new email already exists" after email was previously changed

Hello,

I am using the Management API and doing a basic update on a users email.

Scenario: (This is a testing scenario that will likely be rare in production)

I update the users email using the API api/v2/users/{id}

This update works fine and I verify that the email has been changed in the admin panel.

Then I go to do the same process only changing the email back to the original email.

I get the 400 error here “The specified new email already exists”

Is there some amount of time that an email would remain in the system after being changed.

Thanks,
David

Hey @david.pitzel :wave:

Do you have a Custom Database that uses the “Get User” script? I’ve encountered something like this when I had set up a Custom Database w/ Automatic Migration.

I believe the “Get User” script is called to make sure the email you are changing to does not already exist in your own identity data store outside of Auth0.

Hey @gparascandolo ,

Thanks for the response. It looks like we do have a “Get User” script. Since this fires on a pre trigger before I update our DB it makes perfect sense. Thanks for the heads up.
